The next 'Wireless Battle of the Mesh' will take place from Mon 12th till Sun 18th of May at the Sublab Hackerspace in Leipzig, Germany. The event aims to bring together people from across the globe to test the performance of different routing protocols for ad-hoc networks, like Babel, B.A.T.M.A.N., BMX, OLSR, and 802.11s. Of course, new protocols (working on OpenWrt) are always welcome!
It is not required to be active within the mentioned protocols, so if you are a mesh networking enthusiast, community networking activist, or have an interest in mesh networks in general, you have to check this out!
